Finally, the system performance is compared and verified with the measurement data that have been obtained by practical field experiments. The proposed plant growth measurement system has been designed and implemented using fixed-type and rotary-type infrared sensor based measurement methods and devices. The analyzed data are then provided for administrators and a group of interested users. Once the growth parameters are measured, they are transmitted to a remote server using the sensor network technology and analyzed in the application program server. Non-contact sensors have been used not to cause any damage to plants during measurement of the growth parameters.
The proposed system measures plant growth parameters such as the stem radius of plants using real-time non-contact methods, and generates diameter, cross-sectional area and thickening form of plant stems using this measured data. Non-Contact Plant Growth Measurement Method and System Based on Ubiquitous Sensor Network Technologiesįull Text Available This paper proposes a non-contact plant growth measurement system using infrared sensors based on the ubiquitous sensor network (USN technology. The simulations may reduce the costs of machining processes. The results of non-contact measurements can be used in the simulation studies of grinding processes.
Moreover, the paper presents the possible application of results of conducted investigations. The low reproducibility of contact measurements may be connected with the inaccuracy of the selected coordinate measuring machine and the measuring probe, the measurement parameters and environmental conditions in the laboratory where the coordinate measuring machine is located. The measurements of analyzed grinding pins performed by means of the non-contact measuring system are characterized by higher reproducibility than the contact measurements. On the basis of gained results the guidelines concerning measurements of grinding pins were formulated. Non-contact measurements were conducted by means of the tool presetter produced by the Mahr company. The applied strategies included different scanning velocities and distances between measured points. Contact coordinate measurements were performed by using of different measurement strategies. The used coordinate measuring machine was equipped with the contact scanning probe VAST XT and the Calypso inspection software. In the case of contact measurements the coordinate measuring machine ACCURA II was applied. The measurements were conducted in order to choose the appropriate measuring technique in the case of the considered measurement task.
